RESUMO
A case of superficial angiomyxoma arising in the areola of a 49-yr-old woman is presented, including both fine-needle aspiration cytology (FNAC) and histological study. The aspirate yielded a rich myxoid background with isolated fusiform cells, showing oval, monomorphic nuclei with minimal atypia. Sometimes these cells were arranged in small fragments without any specific pattern. The absence of mitotic figures, atypia, or cutaneous and breast epithelium suggested a benign myxoid stromal neoplasm. The final diagnosis was established on the excised mass by histopathologic study. The report of this entity in FNAC and the differential diagnosis with other myxoid lesions are discussed, and the feasibility of its cytological diagnosis by FNAC, helped by appropriate clinical information.
